a uniform disk and a uniform sphere are rolled down an incline plane from the same point and intially they are at rest. Find the difference in time they arrive at a mark on the plane which is 6 meters from the starting point. The sphere has twice the mass and the same radius as the disk. The disk has a mass of 3kg and a radius of 0.4m. The angle of inclination is 30 degress.
